Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulse riveting, in particular to a handheld pulse machine. Background Art
[0002] Hot riveting deforms or even melts the connection parts of two metals together by increasing the temperature. Pulse riveting is a closed circuit composed of a pulse power supply, a pulse handle and a pulse rivet head. When the button on the pulse handle is turned on, it is equivalent to giving the pulse power supply a "start" electrical signal. After the circuit system in the power supply receives the signal, it detects whether the temperature of the rivet head has reached the set temperature. If it has not reached, the control circuit is in a pass state. If it has reached, the control circuit is in an open state. When the pulse rivet head is processed, its heating resistance has been fixed to R (different rivet heads have different R values). When a voltage of fixed value U is applied to both ends of the rivet head, the rivet head will heat up due to Joule's law. By controlling the time, the rivet head will generate a certain amount of heat, thereby controlling the temperature of the rivet head.
[0003] In actual application, after the product is hot-riveted, it needs to be cooled down quickly. However, the existing riveting pulse machine cannot directly cool down the rivet head. An additional cooling device is required to cool down the rivet head. The operation is not convenient, and it is not accurate to determine whether the temperature reaches the set temperature requirement. Summary of the invention

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figures 1 to 3In the embodiment of the utility model, the handheld pulse machine includes a handheld pulse machine, including a pulse electric box 1 and a pulse handle 5. The pulse electric box 1 and the pulse handle 5 are electrically connected through a wire 3. The output end of the pulse handle 5 is connected to a pulse rivet head 6. The end of the pulse handle 5 close to the pulse rivet head 6 is connected to a connector 7. The connector 7 is an arc-shaped structure, and a chamber 10 is arranged inside the connector 7. A plurality of exhaust holes 9 are opened on the end surface of the connector 7 close to the pulse rivet head 6. An air inlet 8 is arranged on the outer wall of the connector 7, and the air inlet 8 is evenly connected to the exhaust hole 9 and the chamber 10; a micro air compressor 2 is installed at one end of the pulse electric box 1, and the output end of the micro air compressor 2 is connected to the air inlet 8 through a conduit 4; a pulse power supply and a controller are installed inside the pulse electric box 1, and the pulse power supply is electrically connected to the controller; the micro air compressor 2 is electrically connected to the controller.
[0018] In this embodiment: in the actual application process, after the product is hot-riveted, it needs to be cooled down quickly. However, the existing riveting pulse machine cannot directly cool down the rivet head, and an additional cooling device is required to cool down the rivet head. The operation is not convenient, and it is not accurate whether the temperature reaches the set temperature requirement. Therefore, this solution uses a micro air compressor 2 to transport compressed air to the chamber 10 in the connector 7, and then the exhaust hole 9 on the connector 7 sprays and blows air to the pulse rivet head 6 on one side, so that the pulse rivet head 6 can be quickly cooled down.
[0019] It should be noted that the pulse electric box 1, pulse handle 5 and pulse rivet head 6 in this scheme are all existing technologies. The pulse electric box 1, pulse handle 5 and pulse rivet head 6 form a closed circuit. When the button on the pulse handle is started, it is equivalent to giving the controller in the pulse electric box 1 an electrical signal of "start". The pulse handle 5 (containing a temperature sensor) transmits the detection signal to the controller in the pulse electric box 1. When it is detected that the temperature of the pulse rivet head 6 reaches the set temperature value, the controller will control the pulse power supply in the pulse electric box 1 to stop the pulse work. Conversely, when it is detected that the temperature of the pulse rivet head 6 does not reach the set temperature value, the controller controls the pulse power supply to continue to output pulse electricity for the pulse handle 5.
[0020] Specifically, the micro air compressor 2 is also electrically connected to the controller in the pulse electrical box 1. After the product is hot riveted, it needs to be cooled down quickly. At this time, the pulse handle 5 transmits the detected temperature signal to the controller. If the detected temperature signal does not reach the set temperature value, the controller controls the micro air compressor 2 to start working. The micro air compressor 2 delivers compressed air to the chamber 10 in the connecting piece 7 through the conduit 4, and then the exhaust hole 9 on the connecting piece 7 sprays and blows air to the pulse rivet head 6 on one side; if the detected temperature signal reaches the set temperature value, the controller controls the micro air compressor 2 to stop working. It should be noted that the cooling component in this scheme also includes a cooling switch button, which is arranged between the controller and the micro air compressor 2 and electrically connected through a wire; when cooling the pulse rivet head 6, the button on the pulse handle (the closed switch that controls the electrical connection between the pulse electrical box 1 and the pulse handle 5) needs to be turned off to avoid conflicts caused by pulse heating and pulse cooling.
[0021] Please refer to Figure 2 and Figure 3 , a plurality of exhaust holes 9 are arrayed and dispersed on the annular end surface of the connecting piece 7 .
[0022] In this embodiment, the connecting member 7 is close to the pulse rivet head 6, and the exhaust holes 9 on the connecting member 7 are scattered around the pulse rivet head 6. The pulse rivet head 6 is sprayed with high-pressure air, thereby accelerating the air flow rate around the pulse rivet head 6, thereby achieving a rapid cooling effect. The exhaust holes 9 are close to the outer sides of the pulse rivet head 6, which can make the pulse rivet head 6 evenly dissipate heat as a whole, thereby improving the accuracy of temperature detection.
[0023] Please refer to Figure 2 The pulse handle 5 and the connecting piece 7 are connected by threads.
[0024] In this embodiment: the connecting member 7 is threadedly connected to the pulse handle 5, which is convenient for later installation or disassembly, maintenance or replacement; secondly, the connecting member 7 is installed on the pulse handle 5 to facilitate user operation and control.
[0025] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
